My invention relates to counters of the computing type which areparticularly adaptable for use inV apparatus used for dispensinggasoline into tanks of automobiles. Such counters may be used toindicate the quantity of fluid dis-v pensed, or the total cost thereof,or both. Most may be preadiusted to compute the cost of the quantity offluid dispensed in accordance with a visible dial indicated currentprice.

It is an object of my invention to provide improved resetting mechanismadapted to reset to zero the various wheels of both thecountersindicating the quantity and the counters indicating the total cost ofthe fluid dispensed.

Another object of my invention is to provide resetting mechanism adaptedto reset the counter wheels reversely to zero, thereby eliminating theneed for shutters. The various weights and measures bureaus require thatsuch counters, if set forward to zero, shall include shutters adapt'- edto conceal the figures on the counter wheels during the resetting tozero operation.

The primary drive shaft i is adapted to be connected by means of thecoupling 2 with the drive shaft 3 of a conventional type of liquid meteras used in liquid dispensing apparatus of the type for which myinvention is particularly applicable. Said shaft i is Journaled in thebearing bracket l on the bottom closure plate 5, which forms part of thehousing forthe counter mechanism. Said housing also includes the upperplate 6 and side frames 8V and 9 conveniently held together by means ofa series of screws I0.

Said shaft i carries the bevel gear ii conveniently fastened on saidshaft I by means .of the pin i2. Said bevel gear il is in mesh with thebevel gear I3 carried by the shaft il and conveniently fastened on saidshaft I4 by means of the pin I5. Said shaft Il is journaled in thebearings I8 and i1 conveniently formed as bosses on said bottom plate 5.

Said shaft Il carries at its opposite end the gear I8 convenientlyfastened on said shaft by means of the pin i9. Said gear i8 is in meshwith the gear 20 rigidly fastened by screws 2i to the housing 22 of thefriction clutch of the quantity counter. Said clutch housing 22 iscarried by the hub sleeve 36 of the gear 36. Said hub sleeve 3B ismounted with freedom of turning movement on the left hand end of thesleeve, or hollow shaft, 24. The right hand end of said sleeve 24 isJournaled in the side frame member 9. 'I'he leftl hand side of saidclutchA housing 22, as seen in Fig. I, is supported with freedom ofturning movement on the bushing Il.

, The friction clutch is of a conventional type and includes clutchsprings 25, clutch levers 26,

pressure ring 21, clutch driving plate 28, and

disk 25. which disk is interposed between the clutch plate 28 and saidgear 28.

In Fig. I, the elements of the friction clutch are shown in engagedposition. With the clutch in engaged position, the gear 28, the clutchhousing 22 fastened thereto, the hub sleeve 36', and the gear 36 rigidlyfixed on said sleeve 36', turn as a unit upon turning movement of saidgear 28.

Said hollow shaft 24 carries the clutch releasing plunger 3|, the righthand end of which extends beyond said side frame member 9 for engagementwith the bell crank lever 32, as hereinafter described. The plunger rod3| has mounted on the left hand end thereof the thimble 33 forengagement with the clutch levers 26, when said rod 3| is moved to theleft, as hereinafter described. Said thimble 33 is mounted forreciprocal movement in the bushing 34 carried by the left hand sideframe member 8.

The counter mechanism, or totalizer, is of ordinary type and is of thewell-known Veeder- Root construction. Said counter mechanism, ortotalizer, includes the gears 36, 31, and 38; gears 58; two-toothedgears 59; and tens-transfer pinions 39 and 46. Said gears 36, 31, and 38are in integral relation with their respective hub sleeves 36', 51, and63, which sleeves are mounted with freedom of turning movement on saidhollow shaft 24. The transfer pinion 39 is loosely in integral relationwith their respective hub sleeves which are mounted with freedom ofturning movement on the shaft 4| rigidly supported in the bosses 42formed on the bottom closure plate 5. Said transfer pinion 48 is looselymounted on the shaft 44 rigidly supported in the bosses 45 also formedon the bottom closure plate 5.

Said quantity counter generally indicated at A includes two oppositelycounterpart series of numbered wheels, one completeseries of which isshown in Fig, I, including the counter wheel 46 of lowest order andconveniently carrying indicia indicating tenths of a gallon; the counterwheel 41 of next higher order, conveniently carrying indicia indicatingwhole gallons; and the counter wheel 48 of highest order convenientlyindicating tens of gallons. The wheel 58 of lowest order of the seriesat the opposite side is shown in Fig. II. The wheels 46, 41, and 48 arecarried on the shaft 52 mounted in brackets 53, one of which is shown inFig. II. The bank of oppositely counterpart wheels, including the wheel58 of lowest order, is carried by the shaft 54 mounted in brackets 55,one of which is shown in Fig. II. Necessary gearing connections,identical with those shown in Fig. IV for the total cost register, areprovided'for connecting the numbered wheels with their gears 36, 31, and38 ofthe quantity counter mechanism. Thus, the bank of wheels 46, 41,and 46, and the oppositely counterpart bank including the wheel 50 oflowest order, are connected to their respective drive gears 36, 31, and38 in the same manner as the two banks of wheels of the total costcounter shown in Fig. IV, hereinafter described.

The sleeve 51, which is mounted to turn on said sleeve 24, has rigidlyconnected therewith the gear wheel 58 and the ratchet wheel 68, whichwheel 68 has a circular series of ten ratchet notches 6|, as shown inFigs. II and VII. Said wheels are connected by a series of rivets 62.The sleeve 63, likewise mounted to turn on said sleeve 24, also hasconnected therewith a similar gear wheel 58 and ratchet wheel 68. Asbest shown 1n Figs. V, VI, and VII, each of said gears 36, 31, and 38carries a bell crank pawl 65 pivotally conneeted thereto on respectivestuds 66 rigidly mounted on said respective gears 36, 31, and 38. Thepawl tips 61 are adapted to be engaged in notches, or slotted keyways,68 in said sleeve 24 during the resetting-to-zero operation of thecounter. Each of said pawls 65 is spring pressed toward engagingposition in its respective notch 68 in said sleeve 24 by means of spring18. the upper ends of which encircle studs 1| riveted to said gears 36,31, and 38. Each of said pawls 65 has an extending arm 12 carrying aroller 13 pivotally mounted at the end thereof, and adapted forengagement with the arcuate surface 14 of respective tracks 15 when saidtracks 15 are in their engaging positions as shown in Figs. I, II, VI,and VII. When said rollers 13 are thus in engagement with theirrespective tracks 15, the tips 61 of the pawls 65 are held innon-engaging position with respect to their respective notches 68.

The pawls 65 mounted on said gears 31 and 38 have respective ratchetstuds 88, fixed in said pawls, projecting toward the left in Figs. I andVI, so as to engage any one of the notches 6| of their respectiveratchet wheels 68 with which the stud registers. Driving connection isthus formed between the indicia carrying counter wheels and the gearwheels 58 during the counting or registering operation of the mechanism.

Said gear 20 engages the gear 82 driving the variator mechanismindicated generally at C, and including the cone gear 83. The variatormechanism illustrated in Fig. I is of the type shown and described inLetters Patent of the United States granted to Slye et al. No.2,151,239. However, the means for adjusting the varlator shown hereinare an improvement over that shown in said Slye et al. Letters PatentNo. 2,151,239, and such improvement in computer price setting means isclaimed in my Patent 2,295,819, granted September 15, 1942.

The cone gear 83 drives one or more selector gears 84 which in turndrive the cost value gear 85 through differential or planetary gearing86. The total cost register indicated generally by the reference mark Bis driven through the clutch assembly 88 in the housing 89 on which saidgear 85 is rigidly mounted by means of screws 98.

Said clutch 88, similar to the clutch for the quantity register,includes clutch springs 9|, clutch levers 92, pressure ring 93, clutchdriving plate 95, and disk 96, which disk is interposed between theclutch plate and the end closure plate 91 for said clutch housing 89.

The clutch housing 88 is carried by the left hand end of the sleeve, orhollow shaft, 98, the right hand end of which is journaled in the sideframe member 9, as indicated by the reference mark 99.

The hollow shaft 98 carries the clutch releasing plunger |88, the righthand end of which extends beyond the side frame member 9 for engagementwith the bell crank lever arm 32', as hereinafter described. The plungerrod |88 has mounted on the left hand end thereof the thimble |82 forengagement with the clutch levers 92, when said rod is moved to theleft, as hereinafter described. Said thimble |82 is mounted forreciprocal movement in the bushing |83 carried by the left hand sideframe member 8.

The counter mechanism is of ordinary construction and includes the gears|85, |86, and |81, in integral relation with their respective hubsleeves which are mounted with freedom of turning movement on saidhollow shaft 98, and the tens-transfer pinions |08 and |03. The transferpinion |08 is loosely mounted on the shaft ||0 rigidly supported in thebosses formed on the top closure plate 8. Said transfer pinion |08 isloosely mounted on the shaft ||3 rigidly supported in the bosses ||4,also formed on the top closure plate 6.

Said total cost counter generally indicated at B includes two oppositelycounterpart series of numberedy wheels, one complete series of which isshown in Fig. I, including the wheel ||6 of lowest order andconveniently carrying indicia indicating from to "9" cents; the counterwheel ||1 of next higher order, conveniently indicating from 0 to "9"tens of cents; and the counter wheel ||8 of highest order convenientlyindicating from "0 to 9 dollars. The wheel H8 of lowest order of theseries at the opposite side is shown in Fig. II. The wheels ||6, ||1,and ||8 are carried on the shaft |20 mounted in brackets |2|, one ofwhich is shown in Fig. II. The bank of oppositely counterpart wheels,including the wheel ||9 of lowest order, is carried by the shaft |22mounted in brackets |23, one of which is shown in Fig. II. Necessarygearing connections are provided for connecting the numbered wheels withtheir gears |05, |06, and |01 of the total cost register, as shown inFig-IV.

The sleeve |25, which is mounted to turn on said .sleeve 98, has rigidlyconnected therewith the gear wheel |26 and the ratchet Wheel |21. Theratchet wheel |21 has a circular series of ten ratchet notches |28, asshown in Fig. II. Said wheels are connected by a series of rivets |30.The sleeve 3|, likewise mounted to turn on the sleeve 98, also hasconnected therewith a similar gear wheel |26 and ratchet wheel |21.

Each of said gears |05, |06, and |01 carries a bell crank paw1 |32pivotally connected thereto on respective studs |33 rigidly mounted onsaid respective gears |05, |06, and |01. The Dawl tips |34 are adaptedto be engaged in notches, or slotted keyways, |35, in said sleeve 98during the resetting-to-zero operation of the counter. Each of saidpawls |32 is springpressed toward engaging position in its respectivenotch |35 in said sleeve 98 by means of a spring |36, the lower ends ofwhich encircle studs |31 riveted to saidr gears |05, |06, and |01. Eachof said pawls |32 has an extending arm |38 carrying a roller |39pivotally mounted at the end thereof, and adapted for engagement withthe arcuate surface |40 of respective `tracks |40', integrally connectedto the sleeve |4|, when said tracks |40' are in their engaging positionsshown in Figs. I and II. When said rollers |39 are thus in engagementwith their respective arcuate faces |40 of said tracks |40', the tips|34 of the pawls |32 are heldin non-engaging position with respect totheir respective notches |35.

'Ihe pawls |32 mounted on said gears |06 and |01 have respective ratchetstuds |42, fixed in said pawls, projecting toward the left in Fig. I, soas to engage any one of the notches |28 of their re-v spective ratchetwheels |21 with which the stud registers. Driving connection is thusformed between the indicia carrying counter wheels and the gear wheels|26 during the counting or registering operation of the mechanism.

The interlock lever |43, pivotally mounted on the stud |44 in the sideframe member 8, is connected through a suitable linkage member |45 tothe switch controlling the energy to an electric pressure through afluid meter, the drive shaft of which is indicated by the reference mark3. Both the counters for indicating the quantity of fluid dispensed,generally indicated by the reference mark A, and the total cost counter,generally indicated by the reference mark B, are reset to zero by meansof the crank |46 conveniently rigidly connected to the right hand end ofthe shaft |41 by means of the pin |48.

The cup cam |50 and the cup cam |5| are mounted in telescopic relationon the sleeve |41' connected to said shaft |41 by the set screw |49.Said cup cam |50 is provided with the notch |52 and said cup cam |5| isprovided with the notch |53, said notches being in registry when thecams v are in the position shown in Figs. I and II. Said lever |43 hasthe rigid lug |55 adapted to enter the notches |52 and |53 when inregistry with each other. When the lever |43 has been moved clockwiseupwardly to close the motor switch, the lug |55 enters the notches |52and |53 of the respective cup cams |50 and |5 and rotation of the crank|46, shaft |41, etc., is prevented during such time as the motor switchremains closed and the motor is running.

Upward movement of the lever |43 to close the motor switch causes thelever extension |56 to engage the stud |51 carried by the springtensioned lever |58 and turns said lever |58 clockwise and the shaft |59mounted therein. As best shown in Figs. II and VIII, said lever |58 isprovided with the latch |58' for engagement with the lug |43 on saidlever |43. The cam |60 is rigidly connected to the shaft |59, and saidcam |60 is provided with the notched portion |6|. lUpward movement ofsaid lever |58 causes said cam |60 to be turned clockwise with theresult that the notched portion |6| engages the stop frame lever |62 andturns the series of stop assembly arms |63 counterclockwise to disengagethe stops |65 from their respective studs |66 rigidly mounted on theset-back gears |61 and |68 and on said gears 36 and |05. Said stop framelever |62 and the series of assembly arms |63 are integrally connectedto the sleeve |10, the left hand end of which, kas shown in Fig. I, ismounted on the bracket |1| connected to the side frame member 8. Theright hand end of said sleeve is mounted on the bracket' which theroller |80, mounted for free turning' movement on the stud |8| carriedby said lever 32', is engaged during the operation of the countermechanism.

The web portion |5|' of said cup cam- |5| is provided with a series ofarcuate notches .|82 through which the studs |15 of the camA |50project. When the ends of said arcuate slots |82 come into engagementwith the studs 15, the cam motor which drives the pump to force fluidunder 76 back gear |68 rigidly connected to the hollow Shaft 24.

Said cam I5| is provided with the inclined cam face |85 and a horizontalface |86, which latter face is in registry with the underside of thenotch |18 in the cam I 50 when said counter mechanism is in operatingposition, as shown in Figs. I and II. Said cam also carries the stud |81for engagement with said lever |58 during the resetting operation. Atorque spring |88 is provided for said cams, one end of said springbeing anchored around an extension |69 formed on the end of one of saidstuds fixed in said cam |50. The distal end of said spring |88 isfastened to said set screw |49.

The bell crank levers 32 and 32', which respectively engage the clutchreleasing plungers 3| and |00, are respectively pivoted at |90 and 9| inthe bearing brackets |90 and |9| mounted on said side frame member 9.The arm of said lever 32 is bifurcated to receive the stud |8|, theopposite end of which carries the roller |80.

Said lever 32' has connected thereto the lever |94 which is pivotallyconnected at its left hand end to the depending link |95 connected tothe sleeve |4| and tracks |40. The initial rotation of the set-backcrank |46 causes the roller |60 to move to the right in Fig. I, thusmoving the lever 32 counterclockwise in Fig. I. Counterclockwisemovement of the arm 32 also moves the lever |94 counterclockwise. Suchmovement of the lever |94 causes clockwise turning movement of the link|95, in a plane at right angles to the plane of said lever |94, andmoves the sleeve |4|, connected to said link |95, clockwise; thus movingthe arcuate track surfaces 14 and |40 from pawl upholding contact withrollers 13 and |39,

Operation of resetting mechanism The counter resetting mechanismoperates as follows:

The motor switch operating lever |43 is moved upwardly so that the lug|55 has entered the notches |52 and |53 of the cup cams |50 and |5| soas to prevent turning of the crank |46 while the motor is running.During upward movement of the lever |43, the extension |56 on the lever|43 has pushed the stud |51 of the lever |58 upwardly, turning the shaft|59 clockwise, in Figs. II and VII, so that the cam |60 has turned thestop frame lever |62 and the series of stop assembly arms |63counterclockwse to disengage the stops |65 from the studs |66. Theroller tracks 14 and |40 are in position to engage the pawl rollers 13and |39 during part of the travel of the rollers and thereby prevent thepawl tips 61 and |34 from entering the slots 68 and |35 of the hollowshafts 24 and 96.

When the hose nozzle of the gasoline dispensing apparatus for which myinvention is particularly adaptable for use is open, allowing fluid toflow through the meter, the meter shaft 3 drives the shaft clockwise soas to drive the gear and f the quantity register consisting of theconventional transfer gearing and the register wheels 46, 41, and 48 andthe oppositely counterpart series of register wheels on the oppositeside, including the wheel 50 of lowest order. The clutch gear 20 alsodrives the gear 82 attached to the center shaft of the cone gear 83. Thegear 83 drives one or more selector gears 84 which in turn, throughdifferential or planetary gearing 86, drives the gear 85 of the totalcost register. The total cost register gear 85, through the total costregister clutch assembly in Ithe housing 89, drives the total costregister counter generally indicated by the reference mark B, andincluding the oppositely counterpart series of counter wheels H8, ||1,H8, I|8,etc.

After the desired quantity of uid has been dispensed and registered onthe quantity register and simultaneously the cost thereof registered onthe total cost register, the valve of the dispensing hose nozzle isclosed and the motor switch is shut ofi' by counterclockwise movement ofthe switch operating lever |43. Such downward movement of the lever |43dlsengages the lug I 55 from the notches |52 and |53 and also allows thelug |43 to be engaged by the latch |68 under the tension of the latchlever spring, and prevents clockwise movement of the lever 43 to againclose the motor switch until such time as the registers have been resetto zero.

To reset both the quantity and total cost registers to zero and tounlatch the lever |43 to allow closure of the motor switch, the crank|48 is turned clockwise, in Fig. 1I, thus rst turning the cup cam |5|against tension of the torque spring |88 so that the inclined cam face|85 forces the roller toward the crank, and the bell cranks 32 and 32are Iturned on their pivots |80 and |8| moving the plunger rods 3| and|80 to the left so that the thimbles 33 and |82 encounter theirrespective clutch levers 26 and 82. Said bell cranks 32 and 32' are ofstepped shape construction, and said crank 32' has a verticallydepending portion, at right angles, at the right hand end of thehorizontal portion of the crank and has a vertically upstanding portion,at right angles, at the left hand part of the horizontal portion of saidcrank, as shown in Fig. II. The bell crank 32 is formed in the samemanner, except that it is oppositely counterpart to the configuration ofthe crank 32. As the clutch levers 26 andV 92 are pressed to the left,the clutch housings 22 and 89 are locked against the adjacent side framemember 8 to prevent the development of any gear train back-lash, and theclutch springs 25 and 9| are deflected.

lwhich releases the pressure rings 21 and 83 so that the clutch drivingplates 28 and 85 are released, thus permitting the gears 38, 31, 36,|05, |86, and |01 to be set back to zero. During the zeroizing operationwith the friction clutches disengaged, the gears 20, 82, and remainstationary, as disengagement of said clutches permits the left hand endsof the respective hub sleeves of the gears 36 and |05, upon rotationthereof, to turn freely in said gears 20 and 65. 'Ihe lever |94,attached to the upper bell crank 32', turns downwardly at the same timeand by means of the link the roller tracks 14 and |40 are turnedclockwise out of the course oi' the pawl rollers 13 and |39 so that thepawl tips 61 and |34 are stressed against the hollow shafts 24 and 98 bytheir respective springs 10 and |36, regardless of what position thepawls may have been in their course of travel at the time the rollertracks are moved out of support of the rollers.

By continued rotation of the crank, the cup cam |5| continues to turnclockwise until the roller |60 emerges from the notch |18 and the endsof the slots |82 in the web of the cam |5| engage the studs |15 of thecam |50 and begin to drive the set-back gear |11 which is in mesh withthe set-back gear |61 of the total cost register and the set-back gear|68 of the quantity register. Such clockwise movement of the gear |11causes counterclockwise movement of both the counter set-back gears |61and |86 and their respective hollow shafts 98 and 24 to which said gears|61 and |68 are attached. As the hollow shafts 24 and 96 rotate, theslots 88 and |35 coincide with their respective pawl tips 61 and |34 atvarious positions, and the ratchet studs 88 and |42 are disengaged fromrespective notches 8| and |28 in their respective ratchet wheels 88 landvnotched portion |8| ofthe cam |68 to encounter and move the stop framelever |62 clockwise.

Such clockwise movement of the arms |63 causes the stops |85 to engagetheir respective studs |68 mounted on the set-back gears.|61 and |68 andon said gears 36 and |85, thus stopping both the quantity and total costregisters at zero position and also releasing the latch |58 fromengagement with the lug |43' mounted on the lever |43.

' At this point in the cycle of the resetting operation, the roller |88is again alined with the notch |18 in the cam |58. When the set-backcrank |46 is released from the hand of the operator, the torque spring|88 turns said crank |46 and the cam counterclockwise so that the roller|88 is drawn into the notch by the tension spring I8 fastened to a studon the lever 32. I'he distal end of said spring is conveniently iixed onthe supporting bracket |1|. Such drawing of the roller into the notchescauses the engaging tips of the bell crank levers 32 and 32 to be turnedclockwise, thereby releasing 4the plungers 3| and |88 and allowing theclutches in the clutch housings 22 and 88 to again grip their respectivedriving plates 28 and 85.

Such clockwise movement of the bell crank 32' also moves the lever |94clockwise, which causes the link |95 to move upwardly, thereby movingthe arcuate surfaces 14 and |48 of the respective tracks and |48'counterclockwise, so that said tracks again engage with the pawl rollers13 and |39, to thus lift the pawl tips 61 and |34 out of engagement withtheir respective notches 68 and |35; and the transfer gearing mechanismis again connected.

At the end of the resetting operation, the cam notches |52 and |53 areagain in line with the lug |55 of the lever |43, so that the lever |43may be upwardly raised clockwise to close the motor switch. In-suchposition, the engaged in front of their respective studs |66 but, ashereinabove explained, said stops |65 are moved out of position when thelever |43 is raised to start the motor for the next dispensingoperation.
